Wafers and the Like, of which the follow mg is a specification.

The object of my invention is to provide durable and eliicient to bake a large number of Wafers with a-minimum of materials and labor. This object is accomplished by my' invention as will appear below.

Figure 1 is a side elevation, partially in section, of my improved machine. Fig. 2 .is

a similar section, parts omitted, with the,

apparatus in a difierent condition. Fig. 3 is an end elevation'showing the mechanism for supplying batter. Fig. 4 is asect-ional view taken on the line 44 of Fig. 1, looking in the direction of the arrows. Fig. 5'

1s a sectional view of the structure shown in Fig. 4, the mechanism being in a different Fig. 6 is a detailed view showing the driving and clutch mechanism.

Throughout the various views of the drawings, similar reference characters designate similar parts.

My improved machine 1 consists. of a batter supplying mechanism 2 and an oven 3 together with the parts therein contained.

The oven 3 consists of a casing 4 which is' heated in its lower part by a suitable gaspipe 5, or other suitable means, and a ventilated in its upper portion through a suit able flue 6 which may be placed in any suitable location, just as a stove-pipe is placed on a stove. The casing 4 also has a frame 7 which supports the gas-pipe 5 with its burners 8 as well as the mechanism of the oven. The main driving shaft 9 is driven by a suitable fly-wheel 10 and is connected to this shaft 9 by clutch mechanism 11 and carries a pinion 12 that meshes with a large gear-wheel 13 on a shaft 14-which also carries a pinion 15 that meshes with a gear 16 fixed to a shaft 17 journaled in the frame 7. The gears are so arranged and disposed that the angular velocity of the shaft 9 is to the shaft 17 in the ratio-of 8 to .1 so that the flyrwhello makes eight revolutions for everyxrevolutionof. the shaft 17 made in ends ofi fshe carry in The clutch mechanism is so arranged and disposed-that when the treadle 18, is not pressed the fly-wheel 10 stops at the end of every revolution. The details of the clutch form nopart of=my invention.

The shaft 17 is journaled in suitable means of suitable bolts 19, or in any other desired manner; and between these blocks are fixed a pair of hubs 20 from whichradiate suitable spokes 21which are fixed in place by means of cap screws 22 or in any suitable manner. In the embodiment of m invention hereinafter disclosed eight 0 these spokes 21 are shown on each hub makmg sixteen spokes or eightpairs. A greater Patented Feb. 6,1912.

0 blocks 18 which are held-on'the frame 7 by or smaller number of pairs may be employed ifso desired, as the number is not material. Each pair'of spokes 21 carries a wal'fle-iron 23 which consists oftw'o parts, an upper, 24 and a lower, 25, hinged to gether at 26, the part 25 being fixed to the spokes 21 to which the iron is secured and the part 24 is provided with 'a bar 27 which is connected to toggle levers 28 which connect each Waffle-iron 23 with adjacent irons, the part 24 of one being connected tothe part 25 of the next and near the free ends of said irons, that is the ends remote from the shaft 17.

pairs so that the parts 24 and 25 of the waflie-irons 23 will-be firmly compressed when .in use. vided with a projection 29 secured by screws 30 or other suitable means. This projection 29 is one of the elements for causing the iron to be opened and closed in a manner which will be described below.

The spokes 21 are also connected means of suitable bars31 about midway of their length, and these :bars' 31, at or near their centers, carryrbars 32' for shafts 33.

which carry bent arms 34'with rollers 35 at their free ends, to engage the projections 29 and cause the irons 23 toj open or close. These shafts 33 are made squaretatone end and are so arranged that the square end of These toggle levers 28 are- Each part 24 is proone is at the-same end as thero'undedends of adjacent shafts33 so if the even. numbered. shafts 33 have square ends'at the-P right of the machine the odd numbered shafts havetheir squared ends at the left.

This structure; made because the square each instance side of the machine," as well as the connected arts, such as the shaft 38 and roller 37. his structure permits either or both of the rollers. 37 to be put in position to. engage the cams 36.

For convenience the cams 36 are considcred as having two cam surfaces, although,

While the roller 37 it is obvious theyhave butone active surface .as .theparts merge into each other by imperceptible, gradations. One part is the part 41 and the other part is the part 42, and these two parts meet at the pointed exterior.

.the shafts 17 and thereby causes its rollers 35 to press against the projection 29 and open the wattle iron by raising the part 24 from the part 25. As the rotation of the shaft 1.7 continues the cam 36 gets beyond the roller 37 and then its surface 42 comes in contact with this roller. and the weight of the parts is sufficient to keep it against the same, and then the cover 24 of the waffleiron 23 is replaced on the part 25 and the toggle 28 is correspondingly straightened. As the movement continues further a roller 43 mounted on a stud fixed in the frame 7 comes in contact with a roller 45 on a bar 46 on the toggle and presses the'toggle a little beyond the dead center, so that the parts of the-waffle-iron are compressed and opposite function of opening the togglessufficiently so held. A corresponding roller-44 at the lower portion of the frame 7 performs the to make them shift so that they are on the opened side of" the dead center. WVithout this opening it would be impossible for the cam 36 to act, as above described, and the apparatus would be injured or broken.

The batter supply mechanism 2 is placed at one end or one side of the oven 3 and consists of a battertank 47 which receives batter through a suitable opening which is closed by a plug 48 and this tank 47 is provided with an air-pipe 49 and a batter-pipe 50. The air-pipe 49 is connected with an air tank 51 which is supplied by compressed air at a suitable pressure, which comes from any convenient source. The batter pipe 50 runs to a valve 52 which opens and closes in a manner described below and from there ,a pipe 53 runs to an elbow 54 supported in a suitable frame 55 and this elbow connects with a larger pipe 56 which has a stuffing box 57 through which extends a smaller pipe 58 which is adapted to move in the direction of its length and is provided at its outer end with a suitable distributer or'rose 59 which 38 mounted in the frame 7 of engages the part 41 the. free end of the cam 36 is thrown away from" is placed on one side of the machine as shown in Fig. 4 and out of the way of t? operator or it may be located in any 0th r convenient way. The distributing apparatus is run by a wheel, 60 mounted on a suitable shaft 60 which is journaled in the frame 55, and this shaft 60 is parallel to a shaft 61 which is provided with a bar 62 which is fixed on said shaft and provided with a slot at each end, one of which receives a pin 63 on the pipe 58 and the other a pin 60 on the wheel 60, so that by rotating this wheel the pipe 58 is correspondingly shifted for a limited distance. The bar 62 also comes in contact with two rods 64 and 65 which are provided with racks 66 and 67 respectively, these racks meshing with a suitable gear The shaft 69 is supported by a suitable bearing 70 on the frame 55 of the machine and the rods 64 and 65 slide in suitable bearings 71 which are also placed on the frame 55 of the machine. The shaft 69 also carries a suitable beveled gear that meshes with a corresponding gear on a shaft 72 which is vertically disposed and runs through a suitable bearing 73 to the valve 52. This structure results in shutting the valve on or off at appropriate times from the wheel, 60. A hand wheel 61 is also shown on the shaft 61. This may be omitted if desired.

In view of the foregoing the operation of my improved machine for baking wafers and the like will be readily understood. When the machine is in the condition indi- I cated in Fig. 1, the burners 8 are all lighted in the conventional manner and the shaft 17 is put in motion and kept in motion until all the irons 23 are properly heated. When heated, the rollers 37 are thrown into mesh with their respective cams 36 and then the irons 23 are opened as described above, and when opened the clutch mechanism stops the machine as indicate. above. If necessary, a brake may be applied to the shaft 9 or some other shaft so as to cause the machine to stop 'quickly.- As soon as a waflie-iron 23 opens, the operatorturns the wheel 60 in the direction of the arrow in Fig. 3, and, assuming that the apparatus is properly charged with batter, the pipe 58 is run in the direction of its length toward the open iron 23, and then the valve 52 is opened through the mechanism described above, and batter is squirted out over the lower iron 25 and distributed over the same through the rose 59 and then the direction of movement of the bar 62 is reversed, the rose 59 l; withdrawn and the batter shut off and the operatoriplaces his foot on the lever 18 and starts the machine. As soon as the machine is started the iron 23 is closed and the next one is brought up and opened in the manner above described and the toggles made secure on the rollers 43 and opened on the rollers 44 68 mounted on a shaft 69 i ll ori
